⏪If it takes eight men ten hours to build a walk , how long would it take four men ?


❇If you just answer according to simple mathematical calculation , it would take half the time i,e 5 hours .

⭐⭐But according to the question , the wall has already been built by the eight men . So no time is required to build it again .❇❇

Answer 2

Answer:

Either 20 or 0 depending on the context

Explanation:

mathematically the answer is 20. If it takes 8 men 10 hours to build the wall, that means it took 80 man hours. 8 men times the number of hours (8x10=80).  So 80 man hours to build a wall. If you have 4 men, then the equation become 4 men times the number of hours (unknown) to give you 80 hours. so 4x=80. 80/4 will give you x, the number of hours  which is 20 hours.

If you are looking at this from a riddle standpoint, the answer is 0. Since the 8 men have already built the wall in 10 hours, there is no reason for the other 4 men to build the same wall.
